ORANGE, NEW JERSEY, A CORPORATION OF PHONOGRAPHIC RECORDER.

SPECIFICATION forming part .Of Letters Patent N0. 790,542, dated May 23, 1905.

Application filed February 11, 1903. Serial No. 142,891.

To all whom it may concern:

Be it known that I, PETER WEBER, a citizen of the United States, residing at Orange, in the county of Essex and State of New J ersey, have invented a certain new and useful Improvement in PhonographicRecorders, of which the following is a description.

My invention relates to im rovements in phonograph recorders in W 'ch the diaphragm carrying the stylus is in turn supported and carried by a casing movable by gravity, so as to engage the stylus withthe blank, and has for its object to improve the manner of pivotally mounting the diaphragmcasing on the body of the device.

The invention consists in the features hereinafter described and claimed.

In order that the invention may be better understood, attention is directed to the accompanying drawings, forming part of this specification, and in which Figure 1 is a vertical sectional view of a recorder embodying one form of my invention, and Fi 2 a bottom plan view thereof.

In t e above views corresponding parts are represented by the same numerals of reference.

The body 1 is of the usual form, being provided with the usual neck or bore 2 and the depending annulus or flange 3. This flange is cut away at 4 4 4 to form lugs 5 5, through which a straight pivot-pin 6 may be passed from either side. This provides for a very sim le and cheap mode of manufacture. Pivote on the pin 6 is a lug 7, which is secured to a disk-likecasing 8 by soldering or otherwise. The casing 8 is made of sheet metal preferably stam ed in one piece and at its center is forme with an opening having a beaded rim 9. A weighted tube 10 is preferably employed, resting at its lower end on the bead 9 to form a ball-and-socket joint and at its upper end engaging the bore 2, so that the tube is capable of vertical movement with respect to the body 1 and always exerts the desired weight upon the stylus. In the preferred form the casing 8 is rovided with a metallic washer 11, on whic rests the diaphragm 12, made usually of glass or mica. This diaphragm is held in position on the washer 11 by a plastic sealing 13 of waX or similar material. Cemented to the diaphragm 12 is a rib 15, formed with an integral web 16, constituting a socket for receiving the recording-stylus 17. The rib is preferably also formed with flat integral wings 18 which are cemented in place to the dia hragm at or near its center, whereby a very irm and rigid support is offered for the stylus. The rib being cemented to the diaphragm throughout its length and running from the center to the periphery of the diaphragm serves to stiffen the diaphragm sufliciently to prevent objectionable buckling thereof without interfering in any way with the sensitiveness of the diaphragm for recording ordinary sounds.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a phonograph-recorder, the combination with a body having a depending flange formed with cut-away portions to constitute a lug, of a casing pivoted to said lug, a diaphragm carried by said casing, and a recording-stylus connected to the diaphragm, substantially as set forth.

2. In a phonograph-recorder, the combination with a body having a depending flange formed with cut-away portions to form a pair of lugs, of a casing pivoted between said ugs, a diaphragm carried by said casing, and

a recording stylus connected to the diaphragm, substantially as set forth.

This specification signed and witnessed this 4th day of February, 1903.
